Fluorescent glow may reveal hidden life in the cosmos

Astronomers seeking life on distant planets may want to go for the glow. Harsh ultraviolet radiation from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres as they glow. That neon-like glimmer is a star-induced gleam called biofluorescence, which could turn distant exoplanets into the black-light posters of outer-space, according to new Cornell research, published Aug. 13 in Monthly Notices of the Royal Astronomical Society “Biofluorescent Worlds II: Biological Fluorescence Induced by Stellar UV Flares, a New Temporal Biosignature,”

Pictured are the four candidate sample collection sites on asteroid Bennu selected by NASA’s OSIRIS-REx mission. Site Nightingale (top left) is located in Bennu’s northern hemisphere. Sites Kingfisher (top right) and Osprey (bottom left) are located in Bennu’s equatorial region. Site Sandpiper (bottom right) is located in Bennu’s southern hemisphere. In December, one of these sites will be chosen for the mission’s touchdown event.
